Abstract

A novel extraction technique for coconut oil was sought, particularly, the utilization of a switchable hydrophilicity solvent (SHS), N,N-Dimethylcyclohexylamine (DMCHA). Copra samples were obtained, ground to reduce sample size and dried until the moisture was around 7%. Copra samples were used in both SHS and Soxhlet extraction, and oil yields were compared, as well as the oil qualities in terms of%FFA, peroxide value, iodine value, density, and refractive index. The moisture content of copra sample was reported to be ranging from 7-7.2%. The results showed that extraction using the switchable solvent yielded 42.3157±1.6191% coconut oil. SHS-extracted oil has a reported FFA value of 0.12, peroxide value of 13.66±0.7261, iodine value of 11.34±0.84, and refractive index value of 1.44108±0.00048; all of which agreed to the qualities of a crude coconut oil. This study have manifested that SHS based on a lipotropic tertiary amine, N,N-Dimethylcyclohexylamine, can be capably employed most relevantly to the extraction of coconut oil without the use of energy-intensive distillation processes.
